All warnings (new ones prefixed by >>):

>> WARNING: vmlinux.o(.meminit.text+0x153c): Section mismatch in reference from the function __populate_section_memmap() to the function .init.text:memblock_alloc_try_nid()
   The function __meminit __populate_section_memmap() references
   a function __init memblock_alloc_try_nid().
   If memblock_alloc_try_nid is only used by __populate_section_memmap then
   annotate memblock_alloc_try_nid with a matching annotation.
